Anthea X Fem reader (sherlock) 

Summary: while at Mycroft’s office, John meets the girlfriend of Anthea and Sister of Mycroft and Sherlock. 

Third person pov… 

Mycroft Holmes sat in his plush chair, his legs crossed and the ankles and elbows on his desk. In front of him sat John Watson who felt very out of place in the fancy office of his Boyfriends brother. “Sooo how is my baby brother doing Dr” he asked John making the Dr jump at him talking, John cleared his throat and sat up straighter in the chair he was sitting on.  

“Well Sherlock is fine. But I’m sure you already know that Mycroft” sassed the Dr but Mycroft was already very used to people being sassy with him, especially when you have an even younger sibling who is sassy and doesn’t listen to rules. He has learnt to not react or push the person if they are sassy with you.  

“of course,” he gave a fake forced smile to John who can always tell it’s a fake smile, then suddenly the door was slammed open, and Mycroft sighed heavily knowing exactly who it was. “Y/N M/N Holmes! Must you always break down my door with your monster strength. That was my third door just this week” yelled Mycroft angry at the young woman who slammed open the office door, she was tall with long H/C hair and was wearing a smart work outfit.  

Anthea was behind her, Y/N just grinned and kissed Mycroft on the cheek “nope! Sorry not sorry brother” she yelled before plotting down on Mycroft’s desk like she owned the place. “Brother!” yelled John, his yell made everyone in the room to look at him. YNs face lit up when she saw him.  

“So, you must be Sherly’s boyfriend then!” she said making John blush bright red. “Y/N why must you always call us by those ridiculous nick names” sighed Mycroft, the young girl actually ‘sshed’ the man who sighed and put his head on his desk.  

“Oh yeah Myc can Anthea get the rest of the afternoon off” asked Y/N as she then gave her big brother her puppy eyes, which no one could resist or say no too. “Fine! Yes, YN your girlfriend can have the afternoon of to spend with you” yelled Mycroft making the girl cheer and hug her brother tightly “come on love!” Anthea smiled at the two men politely before rushing out after her energetic girlfriend. 

The end!
